Pax Britannica: An Imperial Timeline

"With this principle, you may live to see man-made horrors beyond your comprehension."
- Nikola Tesla




For more than a century, Imperial Britain has ruled over nearly a billion souls, with dominion over every ocean and holdings on every continent. The ancient Habsburg dynasty rules over Central Europe and beyond, the Romanovs stand triumphant from the Baltic to the Pacific, and all the world lies beneath the curtain of a single continent. This was to be the way of things, a planet guided by the light of European civilization. A global imperium to last a thousand years and more.

If only things were so simple.

The power of Tesla's developments ushered in the Second Renaissance, the largest period of technological advancement since the Industrial Revolution. Wireless power brought the unthinkable to life and connected the world, and for a time it seemed Tesla's dream of the happiness of all mankind was in reach. Mankind, however, proved itself unworthy of such lofty goals.

The Great War, waged between the Imperial Powers and the Latin Bourbon dynasties tore the world asunder. The advancements that once sought to end want were turned into blood soaked nightmares. Upstart Japan fell to revolution and civil war, Spain descended into anarchy, and the three hundred year old Bourbon dynasty fell. The world that emerged from the war was battle scarred and traumatized, an entire generation wasted for peace terms.

As the new year dawns in 1933, the world enters a new age of uncertainty. France seeks to regain her place as Europe's dominant power, while Russia has fallen to the tides of bitter revanchism over their mutilated victory. Republican Japan emerges from isolation, ready to unleash the tide of the Pan-Asian Revolution. Across the Atlantic, the United Commonwealth asserts itself more and more, threatening to split the British Empire like Rome of old.

No one can be certain what the future holds, only that the Pax Britannica is about to come to a screeching halt.


Welcome to Pax Britannica: An Imperial Timeline, an alternate history science fiction mod for Hearts of Iron 4.

Taking place in the wake of a failed American Revolution, the mod focuses on the substantial changes this causes in world history, compounded by the success of Nikola Tesla's Wireless Power Concept. The Victorian Era has been flash frozen by this advancement, creating an anarchic mix of the Jazz Age, Wellsian science fiction and transhumanism. The world is both familiar and utterly alien, and the mod seeks to explore that universe and provide a unique style compared to other overhaul mods.

The mod currently contains fully playable content for three countries:
- Britain
- The United Kingdoms of Germany
- France
- The United Commonwealth
- The Second Continental Army

The mod currently contains limited playable content for following countries:
- The Empire of Mexico
